FIELD OF THE INVENTION

The present invention relates generally to providing a telematics systemin a vehicle that has not previously been set up for such a system. Morespecifically, the present invention relates to a simplified telematicssystem for use in a new vehicle at a manufacturing site, or as aretrofitted telematics system to an existing vehicle, and methods forproviding such telematics to a vehicle.

BACKGROUND OF THE INVENTION

As consumer vehicles, such as cars and trucks, become moretechnologically complicated, operation of that vehicle becomes even moredifficult. Today there is such an array of devices in trucks and carsthat driver distraction is a major problem. To ease the driver's burden,mobile telematics systems and services have evolved that integratewireless communications and (usually) location determining devices intovehicles to perform a number of tasks including, for example, carryingout remote engine diagnostics, locating stolen vehicles, and providingroadside assistance. Integration of such telematics systems requiressignificant design and implementation costs, not to mention the costlyhardware that needs to be installed in the vehicle. Even though somemanufacturers have started to include telematics systems with newvehicles, most new vehicles on the road today do not have such systems.More importantly, most manufacturers do not design vehicles to housesuch complex technology. When the manufacturers do incorporate thistechnology, it requires extra wiring and complexity. Thus, a need existsto make simpler systems both for installation at the site ofmanufacturing and retrofitting into existing vehicles without having tomodify the vehicle in any substantial way (whether in terms of cost orlabor).

While most vehicles do not have telematics systems pre-installed, manyvehicles do have other kinds of integrated electronic communicationdevices. One kind of communications device that can be found in somevehicles is a Bluetooth transceiver. Bluetooth is an industrialspecification for wireless personal area networks (PANs). A Bluetoothgateway provides measures for connection and exchanging informationbetween devices such as mobile phones, laptops, PCs, printers, digitalcameras, and video game consoles over a secure, globally unlicensedshort-range radio frequency. Equipping vehicles with a Bluetoothtransceiver (also referred to as a Bluetooth gateway) makes it possibleto link the vehicle with other Bluetooth-compatible devices brought intoor near the car, the most common of which is a Bluetooth-compatible cellphone.

When a Bluetooth-compatible cell phone is brought into a vehicleequipped with a Bluetooth transceiver, a data link is created betweenthe phone and the transceiver. The most common feature made available toowners of vehicles so equipped is the ability to talk on the cell phonein a hands-free manner. In this embodiment, the vehicle is provided witha microphone (at least one near or directed at the head of the driver)for receiving audio from at least the driver (and, possibly, anypassenger within the vehicle). A speaker system commonly associated witha vehicle's radio is temporarily connected to the transceiver and is,thereby, used to present any received audio signals to the user. Ofcourse, dedicated speakers can be provided in the vehicle for thisfunction or even a combination of these exemplary configurations. Withsuch a configuration, bi-directional audio communication is madeavailable to occupants of the vehicle.

Another common Bluetooth feature is the ability to display and/or usethe phone list stored in the cell phone for making calls without havingto touch the cell phone. Either the vehicle is provided with avoice-recognition system to select a particular number in the cellphone's phone number list or has mechanical controls for doing so, orboth. Such systems, however, do not have the ability to expand beyondthese limited functions.

There exists a need to be able to provide a simplified, cost-effectivetelematics system to be used both by original equipment manufacturersfor new vehicle installations and by owners of existing vehicles forretrofitting into vehicles only having a Bluetooth transceiver withouthaving to modify the vehicle in any substantial way (whether in terms ofcost or labor). Even with the advent of telematics systems in vehiclestoday, there is not currently a service that is deployed to solve theabove-described problems. Thus, it would be a significant advancement inthe art to provide a telematics system in a vehicle where one did notexist before and where the vehicle was not pre-configured to providesuch features.

SUMMARY OF THE INVENTION

Briefly, in accordance with the present invention, disclosed is a deviceand method for simplifying manufacturer-fitted telematics systems andretrofitting a telematics communication and control unit in a vehicleconfigured with a Bluetooth transceiver. This system and its processmakes use of existing, in-vehicle Bluetooth gateways (in one embodiment,referred to as a “Sync Box”) by adding a component that contains allneeded additional hardware for carrying out the desired telematicsfunctions, for example, a positioning module (e.g., GPS) and a datamodule. The data module can be a phone with voice capability, but it canalso be merely a data modem. Software is also added. Each vehicleequipped with Bluetooth communications capabilities has a Bluetoothgateway with particular characteristics, which can be obtained from thevehicle's manufacturer. A vehicle-specific software application is addedto the Bluetooth gateway. In this way, the inventive telematicscomponent (also referred to as a telematics gateway) can be linked touser interfaces of the vehicle through the Bluetooth gateway. This linkis achieved through the standard Bluetooth PAN. This softwareapplication contains appropriate logic for activation of the telematicscomponent.

While it is known to use vehicle interfaces to receive and transmitaudio phone calls through a vehicle's Bluetooth gateway, this gatewayhas not been used with data-oriented telematics functions. Where, forexample, the phone does not have service available for communicatingaudio phone calls, the present invention still allows telematicsfunctionality in a vehicle through use of the inventive data-orientedcommunication system. Moreover, the present invention provides thisfunctionality as a retro-fitting system. Thus, the present inventionpermits, for the first time, telematics functionality in a vehiclewithout requiring the vehicle manufacturer to pre-design and pre-installsuch functionality.

In prior-art vehicle telematics components, a dedicated bi-directionalvoice communications link was required. This link was provided byincluding an integrated device containing the same functionality as astandard cellular phone. Concomitantly, charges for this link wereincurred and were at a level comparable to a consumer's pre-existingportable cell phone. Such systems, therefore, caused the consumer to payapproximately double fees for these two cellular devices.

In contrast, the present invention entirely eliminates the need for abi-directional, voice-supporting cellular device to be included in thetelematics component. Instead, the telematics component of the presentinvention needs only to have a data transceiver, also referred to as adata pump. The telematics component can carry out all external datacommunication through this data pump. More specifically, when a userenters a vehicle with a Bluetooth-compatible device, the Bluetoothsystem sets up a communications link between the system and the device.This device can be already recognized (where it has been coupled withthis system in the past) or it can be new to the system (in which case,a recognition protocol between the system and the device is carriedout). The Bluetooth system stores information about each such device ina client stack, in which each such device is uniquely identified andrecorded. The Bluetooth system is, then, able to direct data to, from,and through each such device in parallel or by multiplexing. Thetelematics component of the present invention utilizes this informationand connection to communicate outside the vehicle for voice. Forexample, if a request for information is transmitted out from thetelematics component, the path for such a communication will be betweenthe data pump and the Bluetooth system, which data pump is capable ofsending out the query data and receiving back the answer data. Byknowing which devices are paired, the telematics component can embed theunique calling identifier (e.g., the cellular phone number) within thetransmitted data. Then, when the off-site telematics informationprovider responds to the query, the response is channeled automaticallythrough the paired device. The transaction can be entirely non-voice, inwhich the user is entirely unaware that their data pump was used forthis telematics request, or can include (partially or wholly) voicedata. In the latter case, the user's phone will ring, just as receivinga phone call, and the voice response from the telematics operator(whether automated, recorded or live) is conveyed to the vehicle user.In an alternative exemplary embodiment, the telematics component doesnot embed the unique calling identifier and calls a particularpre-programmed cell phone that is set by the system or the user toreceive a call when a given event occurs.

If there is a reason to originate data from a telematics operator to thevehicle or an occupant of the vehicle, the data is sent through the datapump. Then, when a mobile terminated communication occurs (i.e., to thevehicle), each of these paired devices is polled to determine if theyare currently paired with the telematics component. When such a queryreturns a positive result, the data can be communicated (e.g.,displayed) to the current user through one of the currently paireddevices.

Thus, the present invention entirely eliminates the need for avoice-capable cellular device to be included with the telematicscomponent. By utilizing the vehicle's Bluetooth gateway, the presentinvention can take hold, temporarily, of the consumer's portable cellphone to carry out the needed telematics voice communication, resultingin a significant cost savings.

The invention provides a simplified manufacturer's install orretrofitting telematics system and method for providing telematics to avehicle that overcome the hereinafore-mentioned disadvantages of theheretofore-known devices and methods of this general type and thatprovides a telematics system in a vehicle that has not previously beenset up for such a system.

DETAILED DESCRIPTION

Herein various embodiment of the present invention are described. Inmany of the different embodiments, features are similar. Therefore, toavoid redundancy, repetitive description of these similar features maynot be made in some circumstances. It shall be understood, however, thatdescription of a first-appearing feature applies to the later describedsimilar feature and each respective description, therefore, is to beincorporated therein without such repetition.

FIG. 1 shows a diagrammatic illustration of an exemplary telematicscomponent 10 according to the invention. In this embodiment, thetelematics component 10 includes a Global Positioning System (GPS)device 11, a data pump 12, and a Bluetooth transceiver 13. Each of thesesub-systems is connected to a central controller 14, which can be acentral processing unit (CPU), such as a microprocessor. Othertelematics sub-systems can also be included in the telematics component10 as desired. The telematics component 10 is installed (arrow A) in avehicle 20 having a gateway 21 containing a Bluetooth transceiver 22.Power can be supplied to the component 10 either through aself-contained battery pack or a hard-wired connection to a power supplyof the vehicle (e.g., the battery).

The GPS device 11 is self-contained and, with the CPU 14 and appropriateinternal software, is able to output any desired GPS data (e.g., time orposition in various units or formats). The data pump 12 is configured toreceive and supply data to the Bluetooth transceiver 13 for processingby the gateway 21 or CPU 14. Such data will be addressed in furtherdetail below. The Bluetooth transceiver 13 is configured as a standardBluetooth interface so that the telematics component 10 is recognizedand paired just like any other device after the appropriateacknowledgement routine is carried out. Alternatively, the telematicscomponent 10 can be hardwired into the vehicle.

It is noted that each vehicle 20 can have its own kind of gateway 21.Thus, display, control, and all other functions capable of being carriedout by the gateway 21 will most likely be device-specific. Accordingly,the telematics component 10 is configured with appropriate software 15for interfacing with each of the different gateways 21 presented forconnection. In one embodiment, the telematics component 10 can beconfigured to operate with a single, specific gateway 21. Thus,different telematics components 10 a-n are created, one for each of thepossible gateways 21. In such a case, the vehicle 20 in which thecomponent 10 a-n is to be installed is identified and the appropriatecomponent 10 a-n is used. Alternatively, the component 10 can beconfigured with all possible gateway interface operating configurationsand, upon installation can be programmed to execute the appropriateconfiguration for that specific gateway 21. This execution can be manual(based upon user input of the corresponding vehicle identification) orcan be automatic (through a sequence of question and answertransmissions to the gateway 21). Specifications of each gateway 21 maybe provided by the vehicle manufacture so that the software 15 can bedeveloped accordingly.

The customized software 15 enables a single GPS system 11, a single datasystem 12, and a single Bluetooth system 13 to be customized forinterfacing with any functionality operable by or through the vehicle'sgateway 21. Thus, even if the vehicle was not designed to provide GPSfunctionality, as long as the gateway 21 has a display (or is connectedto a display) and as long as that display's specifications have beenprovided beforehand, the software 15 can format the call status/progressupdates into a form suitable for projection by the existing display tothe user.

As set forth above, standard gateways 21 have the ability to interfacewith cell phones 30 that are present in or near the vehicle 20.Communication can occur from the vehicle 20 through the cell phone 30 toa third party or from a third party to the cell phone 30 (e.g., SMStext) or through the cell phone 30 to the occupant in the vehicle 20(e.g., voice call). The telematics component 10 is able to expand uponthis ability to bi-directionally communicate outside the vehicle 20 bylinking to the cell phone 30 through the gateway 21. Because thetelematics component 10 has the ability to communicate any data itdesires over the Bluetooth transmission channel 40 (i.e., the Bluetoothgateway), it can, for example, obtain the current paired client list ofthe Bluetooth 22 device in the gateway 21, and use one (or more) of thepaired devices remotely through the secondary Bluetooth transmissionchannel 50. More specifically, if the telematics component 10 needed tosend a message to a base station 60, then the data pump 12 wouldconfigure the appropriate data to be transmitted along with relevantcontrol logic. Once the data pump 12 acknowledged that thecommunications channel 71 to the base station 60 was open (which statethe telematics component 10 could detect), the control logic would thencause the appropriate data to be transmitted to the base station 60. Thepresent invention, therefore, entirely eliminates the need for abi-directional, voice-supporting cellular device to be included in thetelematics component 10.

There are a number of exemplary uses for the telematics component 10 soconfigured. One exemplary use is the most commonly found use of atelematics device—to summon roadside assistance. For the presentexample, the entity supplying the telematics component 10 has liveoperators at a remote facility, e.g., at the base station 60, forproviding roadside assistance through a voice communication. Further,the telematics component 10 has a user interface control (which is notillustrated in FIG. 1 but could include software on gateway 21) thatcalls the operator center upon a single actuation. For example, thetelematics component 10 can have a red “emergency” button that, whenpressed, opens a communications channel to the operator. Accordingly,when the vehicle occupant presses the button, the appropriate software15 is called up to enable a “live-operator-communication.” The software15 communicates via Bluetooth 13 to Bluetooth 22 to receive the activepaired phones list. The active paired phones list is then passed to thedata pump 12. Whatever additional data is needed for this operation(e.g., the destination address for the data center at the base station60) is used by the data pump 12. The data pump 12 then triggers thegateway 21, which requires a first paired device (i.e., the cell phone30) to receive a phone call from the base station 60, thus, carrying outthe desired “live-operator-communication” function.

If, as shown in FIG. 1, the telematics component 10 has an embedded GPSsystem 11, the data sent to the base station 60 can include current GPSlocation coordinates. In this way, the operator could be provided withthe information pinpointing the vehicle's location before voicecommunication occurs between the operator and the occupant.

Beneficial to the inventive system and process is the ability to utilizeany Bluetooth communication device within range of the vehicle 20.Whether or not the device has already been recognized (i.e., coupledwith the gateway 21 in the past) or is new to the system (in which case,a recognition protocol between the system and the device may need to becarried out), if the Bluetooth system 22 has the device's identificationinformation in its client stack, then the telematics component 10 hasthe possibility of directing calls to and through each such device asdesired. In normal use, however, the telematics component 10 merelyretrieves the identity of all currently paired devices from Bluetooth22. If desired, the component 10 can periodically communicate thisinformation to the base station 60, which keeps a vehicle-specificpaired-device list.

Roadside assistance is only one of the possible telematics functionsthat could be provided with the inventive telematics component 10 of thepresent invention. Another function that could be provided with thecomponent 10 is a door-unlock command. If the gateway 21 iscommunicatively coupled with the device that unlocks a locked door ofthe vehicle, then the telematics component 10 can interface with thedoor-unlocking device. As set forth above, the manufacturer provides thespecifications for causing the gateway 21 to actuate the door-unlockingdevice. The telematics controller 10 stores this data internally. Afterappropriate authentication, the operator can transmit the pre-programmedauthorization command to the telematics controller 10 via the data pump12. When the telematics controller 10 receives the authorizationcommand, the appropriate control logic is sent to the gateway 21 toactivate the door-opening device. If the gateway 21 is similarlyconnected to the vehicle starting assembly, then the telematicscontroller 10 can effect a remote engine start with little addeddifficulty. Likewise, if the gateway 21 has access to the vehicle'sdiagnostics bus, then any available diagnostic status can be madeaccessible not only to the driver, but also to an operator at the basestation 60. In an emergency, where the driver/passenger(s) is notavailable, the telematics controller 10 can be programmed toautomatically send a diagnostics state(s) to the base station 60.

For example and with reference to FIG. 2, after an event occurs thatrequires the telematics software to take an action, referred to hereinas an event call, the base station 60 can be provided automatically withboth diagnostics data and GPS position data. Also sent to the basestation 60 is the cell phone number for one or more currently pairedcell phones 30 within the Bluetooth PAN of the vehicle 20. Uponreceiving the event call, an operator can be directed to call any or allof the currently paired cell phones 30 associated with that vehicle 20.

More specifically, reference is made to the flow chart of FIG. 3 todescribe this process. Beginning in Step 100, the system waits for anevent call. When an event call occurs, an event signal is sent to thegateway 21 in Step 200. The telematics software on the gateway 21recognizes receipt of the event call. In Step 300, the telematicssoftware notifies the telematics controller 10 and sends the appropriatedata to the telematics controller 10 to list at least one cell phone 30in the Bluetooth stack of the gateway 21. In Step 400, the telematicscontroller 10 sends an event call signal to the base station 60 andnotifies the gateway 21 that the data was sent. The cell phone 30receives a call from the base station 60 connecting the cell phone audioto the base station 60 in Step 500. If desired, audio from the cellphone 30 can be routed to the vehicle's speakers to the occupant viaBluetooth 22. In this way, by having the base station 60 call thevehicle directly, the inventive system avoids an issue that has plaguedthe telematics industry since its early days—bad Caller-ID.Additionally, or alternatively, the base station 60 can have a fallbackphone number for such an emergency and, simultaneously or thereafter,can require an operator to call that phone number.

Deployment of an airbag and the resulting communication with theinvention is described with reference to FIG. 4. After an air bag isdeployed, the base station 60 needs to be provided with both diagnosticsdata and GPS position data. More specifically, an airbag trigger signalis sent to the gateway 21. The telematics software on the gateway 21recognizes receipt by the gateway 21 of the airbag trigger. Thetelematics software notifies the telematics controller 10 and sends theappropriate data to the telematics controller 10 send notification tothe base station and to list at least one cell phone 30 in the Bluetoothstack of the gateway 21. The telematics controller 10 sends an airbagdeployment signal to the base station 60 and notifies the gateway 21that the data was sent. Also sent to the base station 60 is the cellphone number for one or more currently paired cell phones 30 within theBluetooth PAN of the vehicle 20. Upon receiving an accident indication,an operator can be directed to call any or all of the currently pairedcell phones 30 associated with that vehicle 20. The cell phone 30receives a call from the base station 60 informing the user of the cellphone of the airbag deployment. If desired, audio from the cell phone 30can be routed to the vehicle's speakers to the occupant via Bluetooth22.

There are instances where the driver/owner of the vehicle 20 should benotified about current conditions of the vehicle 20. For example, if thevehicle's alarm system activates and the driver is not within range ofthe vehicle 20, then the operator at the base station 60 can be silentlyinformed of the alarm's activation and call a pre-programmed cell phone,such as the owner's phone, or can be asked to call the police with GPSposition information of the vehicle 20.

Other telematics functions require information from the GPS module 11.If position, direction, and speed are made available to the software 15and base station 60 from the telematics controller 10, then it ispossible to carry out, for example, speed alerts, real-time remotevehicle location requests, geo-fencing, stolen vehicle recoveryprocedures, and updates for traffic, weather and/or parking. If thein-vehicle display controlled by the gateway 21 is sufficiently robust,then navigation, point-of-interest, and trip-planning features can bemade available to the driver without installing a costly navigationsystem in the vehicle.
